The seat 61 is rotated with its axis of rotation being parallel to the axis of rotation of the working turret 14, that is, the seat 61 and the working turret 14 are both rotated with the vertical line as the axis. Normally, the operation chamber 6 is provided in the work turret 14, and when the operator does not drive the seat 61 alone, the seat 61 and the work turret 14 are kept relatively stationary, and at this time, the movement state of the seat 61 and the movement state of the work turret 14 are kept consistent; when the operator rotates the seat 61 by itself, the seat 61 rotates around the axis with respect to the work turret 14.

The two operation consoles of the railway working vehicle are respectively connected to the articulated arm 2 and the boom 3, and are specifically, for example, a first operation console connected to the articulated arm 2 and a second operation console connected to the boom 3. The first operation console can control the multi-joint mechanical arm 2 to act, so that the multi-joint mechanical arm 2 drives an operation accessory connected with the multi-joint mechanical arm 2 to construct a railway; the second operation console can control the movement of the lifting operation arm 3, so that the lifting operation arm 3 drives the operation accessory connected with the lifting operation arm 3 to carry out railway construction.

The first operation console and the second operation console may control the traveling of the vehicle body 1 in addition to drive control of the articulated robot 2 and the boom 3, respectively. In short, an operator in the first operation console can operate the multi-joint mechanical arm 2 and the operation accessory connected with the multi-joint mechanical arm to execute specific construction operation, and can also operate the vehicle body 1 to travel along the rail, so that the specific construction operation is better assisted, bidirectional travelling and operation are facilitated, and the requirement of single operation is met.

In addition, a main control room is usually provided in the vehicle body 1, and the priority of the main control room for controlling the traveling and braking of the vehicle body 1 is higher than the priority of the first and second operation consoles for controlling the vehicle body 1.

The operation room 6 may include a main control room 9 provided in the middle of the vehicle body 1 in the longitudinal direction, in addition to the seat 61 and the operation console. The master control room 9 is internally provided with a control platform 92, a master control room electrical cabinet 91, a master control room seat 93 and the like, so that the running, braking and monitoring of the whole vehicle can be realized, and the off-vehicle operation devices such as an oiling device 7 and a fragment supplementing device 8 mentioned below are controlled.

Further, the utility model provides a railway operation car still is equipped with oiling station 7, and oiling station 7 locates the bottom of automobile body 1 for to 01 fat liquoring of sleeper fastener, satisfy sleeper fastener 01's maintenance demand.

The oiling device 7 can supply lubricating oil to the sleeper fastener 01 in various ways, including but not limited to oil spraying and oil dripping. Taking the oiling device 7 for spraying oil to the sleeper fastener 01 as an example, the oiling device 7 adopted by the utility model can specifically comprise an oil reservoir 71, an oil spraying port and a fastener detector; the oil spout is equipped with the control valve, and this control valve and fastener detector all connect in same controller, and the controller adjusts the aperture of control valve according to the testing result of fastener detector to the oil spout state of control oil spout.

Illustratively, when the car body 1 travels along the rail, the fastener detector is normally open for detecting the position of the tie fastener 01 relative to the car body 1. When the fastener detector detects that the oil injection port at the bottom of the car body 1 is aligned with the sleeper fastener 01, the fastener detector sends a first signal to the controller, and the controller controls the control valve of the oil injection port to open according to the first signal, so that the lubricating oil in the oil reservoir 71 is injected to the sleeper fastener 01 from the oil injection port. When the fastener detector detects that the oil nozzle at the bottom of the car body 1 is not aligned with the sleeper fastener 01, the fastener detector sends a second signal to the controller, the controller controls the control valve of the oil nozzle to close according to the second signal, and the oil nozzle stops injecting.

In order to accurately control the oil injection range, when the fastener detector detects that the oil injection port at the bottom of the car body 1 is aligned to the sleeper fastener 01, the oil injection port is firstly controlled to descend by the oiling driver 72, the oil injection port is closely aligned to the sleeper fastener 01, and meanwhile, the car body 1 can also be driven at a low speed, so that fixed-point quantitative oiling to the sleeper fastener 01 is realized.

Therefore, in the walking process of the vehicle body 1, the controller enables the oiling device 7 to intermittently spray lubricating oil, so that oil spraying maintenance of the plurality of sleeper fasteners 01 arranged along the length direction of the rail 02 is realized.

In addition, the bottom of the vehicle body 1 can be further provided with a ballast supplementing device 8 for automatically throwing the railway ballast 03 between the adjacent sleepers 04, so that the railway ballast can be rapidly supplemented when the vehicle body 1 runs along the rail.

The ballast supplementing device 8 specifically comprises a hopper 81 for containing a railway ballast 03, a ballast port driver 82 arranged at a ballast discharging port 811 of the hopper 81 and a sleeper detector for detecting the position of a sleeper of a railway; the ballast port driver 82 is used for controlling the opening and closing of the ballast discharging port 811 and can also be used for controlling the opening of the ballast discharging port 811, and the structure of the ballast discharging port driver can be similar to a valve. The ballast port driver 82 and the sleeper detector are both connected to the same controller, so that the controller controls the ballast port driver 82 to act according to the detection result of the sleeper detector.

In order to simplify the ballast supplementing operation of the railway operation vehicle, the shape and the size of the ballast discharging port 811 can be matched with the shape and the size of the gap between the adjacent sleepers 04 in the railway. For example, when the vehicle body 1 travels along the track until the ballast discharging port 811 aligns with a gap between any pair of adjacent sleepers 04, the projection of the ballast discharging port 811 on the track laying surface may exactly coincide with the gap between the adjacent sleepers 04, that is, the projection of the ballast discharging port 811 on the track laying surface has the same shape as the gap between the adjacent sleepers 04, and the projection of the ballast discharging port 811 on the track laying surface has the same size as the gap between the adjacent sleepers 04. For another example, when the vehicle body 1 travels along the track until the ballast discharging port 811 aligns with the gap between any pair of adjacent sleepers 04, the projection of the ballast discharging port 811 on the track laying surface may overlap the middle of the gap between the adjacent sleepers 04, at this time, the projection range of the ballast discharging port 811 on the track laying surface is in the middle of the gap between the adjacent sleepers 04, and the gap between the adjacent sleepers 04 is greater than the projection range.

Generally, in the embodiment provided by the utility model, unload the projection of tiny fragments of stone, coal, etc. mouth 811 in the track laying face and slightly littleer than adjacent sleeper 04's clearance to unload tiny fragments of stone, coal, etc. mouth 811 and once only put in proper amount railway ballast 03 to between adjacent sleeper 04, avoid railway ballast 03 to drop in sleeper 04 simultaneously.
